FFT 1.3 is a fan-made modification of Squaresoft's game Final Fantasy Tactics for the Playstation and Playstation Portable gaming systems. It greatly increases the difficulty of the game and rebalances gameplay mechanics. 1.3 is not a storyline patch and does not affect the game's plot or character development.

The 13038 patch adds White, Green and Dark Chocobos to the game, turns Boco into White Chocobo (recruitable) and fixes a bunch of balance issues. It makes the Deep Dungeon easier and more fun to play and replaces Ramza's Chapter 4 ability with Heretic Sword, a very useful attack.
